gradle常见设置

gradle配置

虽说自从转到android studio上开发后，接触gradle构建项目，但对于用法上还是模糊，经常用到的就一些配置，至于脚本也就在apk命名上用到，更高阶的脚本会在往后去了解

这些是在实际开发中碰到一些问题，以下会挑一些常用到的配置

支持ndk

gradle.properties

android.useDeprecatedNdk = true

apk打包时包含所需平台so

ndk {
      abiFilters 'armeabi-v7a', 'x86' //只提取两种so
}

打包时排除的文件，可以是so，也会是META-INF下的文件当初在解决64架位上用到，android的系统会优先历遍64下的so，如果不补全，造成so缺失，就会引起找不到相应so的异常

//移除fresco 64架构的so
packagingOptions{
    	exclude 'lib/arm64-v8a/libbitmaps.so'
	exclude 'lib/arm64-v8a/libgifimage.so'
	exclude 'lib/arm64-v8a/libimagepipeline.so'
	exclude 'lib/arm64-v8a/libmemchunk.so'
	exclude 'lib/arm64-v8a/libwebp.so'
	exclude 'lib/arm64-v8a/libwebpimage.so'
	exclude 'lib/x86_64/libbitmaps.so'
	exclude 'lib/x86_64/libgifimage.so'
	exclude 'lib/x86_64/libimagepipeline.so'
	exclude 'lib/x86_64/libmemchunk.so'
	exclude 'lib/x86_64/libwebp.so'
	exclude 'lib/x86_64/libwebpimage.so'
}

签名

android {
    signingConfigs {
        release {
            storeFile file("myreleasekey.keystore")
            storePassword "123"
            keyAlias "fylder"
            keyPassword "123"
        }
        debug {
            storeFile file("mydebugkey.keystore")
            storePassword "123"
            keyAlias "fylder"
            keyPassword "123"
        }
    }

    defaultConfig {
        signingConfig signingConfigs.debug
    }
    buildTypes {
	debug {
            signingConfig signingConfigs.debug
        }
        release {
            signingConfig signingConfigs.release
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            zipAlignEnabled true
        }
    }
}

ps:本地key配置，可将口令和密码在local.properties文件下，防止上传同步

keystore.alias=剑指锁妖塔
keystore.password=123
keystore.store_file=H\:\\photo\\fylder.jks
keystore.store_password=123

 signingConfigs {
        config {
            Properties properties = new Properties()
            //newDataInputStream()读取会出现中文乱码，采用读取字符，而不用读取字节
            properties.load(project.rootProject.file('local.properties').newReader())
            
            def ALIAS = properties.getProperty('keystore.alias')
            def PASSWORD = properties.getProperty('keystore.password')
            def STORE_FILE = properties.getProperty('keystore.store_file')
            def STORE_PASSWORD = properties.getProperty('keystore.store_password')

            keyAlias ALIAS
            keyPassword PASSWORD
            storeFile file(STORE_FILE)
            storePassword STORE_PASSWORD
        }
    }

定义apk名字

android {
 buildTypes {
        debug {
            applicationVariants.all { variant ->
                versionApk(variant, defaultConfig)
            }
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            applicationVariants.all { variant ->
                versionApk(variant, defaultConfig)
            }
        }
    }
}

// 定义输出apk的文件名
// debug和release都追加版本,release带有生成日期
def versionApk(variant, defaultConfig) {
    def today = new Date()
    variant.outputs.each { output ->
        def file = output.outputFile
        def appName = ".apk"
        if (variant.name.equals("debug")) {
            appName = "-v" + defaultConfig.versionName + ".apk"
        } else if (variant.name.equals("release")) {
            appName = "-v" + defaultConfig.versionName + "-" + today.format('yyyyMMdd') + ".apk"
        }
        output.outputFile = new File(
                file.parent,
                file.name.replace(".apk", appName))//更换apkName
    }
}

支持lambda

build.gradle

dependencies {  
        classpath 'me.tatarka:gradle-retrolambda:3.2.5'
    }

app.gradle

apply plugin: 'me.tatarka.retrolambda'

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
